  • Can I add solar panels to an Interlock Metal Roofing System?

    All our products are solar compatible. Our solar brackets can be installed to house solar crystalline panels.

  • How much does an Interlock Metal Roofing System cost?

    Our product is not an off-the-shelf roofing material. Plus the installation procedures vary from structure to structure. For instance, a home with a 3/12 pitch is easier for our installers to work on therefore labour costs will be less expensive. A home with no valleys, chimneys, skylights, or dormers will also be less expensive. Please contact Laurie for pricing info.

  • Are metal roofs loud?

  • Do you offer financing?

    Yes! We’ve partnered with Financeit and Simply Financing Group to offer you affordable monthly, bi-weekly and weekly payment options for your purchase. Visit our Financing page for more info.

  • Does a metal roof attract lightning?

    No, a metal roof will not make lightning more likely to strike, but it may make a lightning strike less dangerous if it occurs. A conductive metal roof gives lightning a low-resistance path to the earth.

  • Are metal roofs hot?

    All Interlock Metal Roofs are coated with the Alunar® Coating System. The "Cool Roof" ceramic pigment technology in the coating reflects and emits more of the sun's UV rays from entering the attic space. Interlock Metal Roofing Systems are energy-efficient CRRC rated (Cool Roof Rating Council).

  • Do metal roofs protect against hail?

    All Interlock® Roofs are made from heavy gauge aluminum which has been tested and has surpassed the industry standard measurement for impact resistance: UL 2218 — Standard for Impact Resistance of Prepared Roof Covering Materials.

  • Can you walk on a metal roof?

    While it is safe to walk on, in accordance with manufacturers’ instructions, the low-maintenance Interlock® Roof almost eliminates that need. 

  • What metal is an Interlock Roof made from?

    All Interlock® Roofs are available in heavy gauge aluminum coated with the Alunar Coating System.


    In addition, solid copper is also available in all profiles.

  • Can I install an Interlock Roof myself?

    While some of us enjoy a good DIY project, to keep the integrity of our Lifetime Limited Warranty we only use certified Interlock crews for installation.

  • Is Interlock Roofing available in my area?

    Interlock Lifetime Metal Roofing Systems are available all across Southern Ontario.
